Should this happen with TC 1 mode?

[dragonflyTN]

Sunny day, mid 50's I am turning right onto a 4 lane from a side street. Fast traffic coming, so I get on the throttle.

Rear end slides around, enough so I tap a foot down to right the bike.

I think: "That shouldn't happen unless I shut the traction control off." Look down to check and the display shows TC 1. So, I loop back around to see if there is oil or something on that corner. Nothing - dry as a bone.

Am I wrong in thinking that TC should have kicked in and kept the tail from drifting?

I read in one of the manuals that traction control doesn't help in a turn. The wheel is sliding sideways and the TC can't account for those situations. I'll see if I can find out where I saw that.

My couple of experiences with TC1 is that it does allow you to slip/slide, but only enough so that you don't get into trouble. The slide itself could have been caused by almost anything. Something on your tire, a flattened can, paper, etc. Hard to say. R

If you have the service manual, it's on page 1-29 where it states the TC cannot recover from a slide. It measures a difference in wheel speed and cuts power through various means to regain traction.

I had the same thoughts early on with the S10. I had pulled off the road to look at some deer. The road had a big lip. When starting back up the rear wheel hit the lip and broke loose. This brought the rear around about 60 degrees. Hmmmm. Didn't think it would work that way.

After thinking about it at home that evening it occurred to me that the bike didn't fall. It didn't feel out of control. Just came kind of came around. Maybe TC1 did its job. With that big engine revving quickly before I realized what was happening and chopped the throttle I could have had a very different outcome...

Thanks for the replies. Come to think of it, I would guess if that slide had happened on my FJR I probably would have crashed.

You need the MSC on the new KTM for what you experienced.

The Yamaha TSC only compares wheel speeds. You probably were sliding sideways with similar enough wheel speeds that the system didn't intervene.

With the KTM MSC, an accelerometer is added to the equation to detect what you experienced and curb it.

I've lost the rear end in a left hander and had to lay 'er down. New (cold) tires, cold/damp road and too much throttle. I saw Blinky come on but by then I was scraping hard parts. I'm just glad the cager behind didn't run me over.

I'm thinking when TC is working at its best, you don't realize it's working at all. That's what I'm thinking. R. ::008::

I love the blinky blinky. Tells me she has my back.

What kind of tires?

Shinko 705, brand new, probably 3 total turns on it when I went down. My mistake for gagging it when 2 lanes turned to 3 and I saw an opening to filter through traffic. Hopefully, next time, I'll remember to get a few miles on the tire before any aggressive cornering.

Anakee 3s with about 800 miles on them... Really couldn't see any reason for a slide. I've gotten on the throttle a lot harder in corners on my FJR. I realize torque characteristics are different and tires are different, but never had that happen "by accident" before without some sort of recognizable cause.

There may be a diagnostic check in your future, not sure if there is one that will help, but couldn't hurt to ask.

But as others have stated, there are circumstances that no electronic controls can fix and many variables that affect how they work.
The Ten just interrupts power when it detects a differential in front and rear tire rotation speeds. Even if a slide was started with excessive power, and the TC kicked in and lowered the power to the rear wheel some sideways movement may have already been initiated. Cutting power does not always stop that. Think of a car, that for whatever reason, has started to spin out {black ice, paper, a can, oil, abrupt yank of the wheel while texting} no ABS or TC stops that, it can help, it can lessen it, but once spinning a lot of that electronic input too late. It's intent is to prevent that spin from happening, but if you do get into the spin it loses much of its effective ability.

My guess is operator error...not picking on you, we all slip at times. ::021::

I love the blinky blinky. Tells me she has my back.

Funny, I'm usually slightly annoyed when I see blinky, blinky. It means I'm not getting all the power I wanted.

Unless it's raining or some other undesirable slippery condition, then I'm very happy to see blinky, blinky.

I'm pretty schizo. :

I never run TC in dry conditions. I even turned off yesterday in the rain when it looked like when were going to hit some clear...I hate that stinking light blinking. Yesterday with Greg it in the rain there were sections it looked like Christmas on my dash between ABS and TC flashing... ::013::

If your ABS light was blinking you may want to check that out. Light only comes on when there is a fault in the system. TCS on the other hand blinks constantly.

Outta sight is outta mind for me.

My height combined with my helmet's lower portion that blocks my view of the cluster unless "I look down specifically" means I see nothing down there.

And yes, I am that asshole riding with his blinker on more often than I would like.

That being said, I feel the TC coming on all the time on these washboard gravel roads cause I never remember to stop and turn the TC off. Very frustrating to have stop to kill the TC. As in that other thread... an on-the-fly TC control function would be very nice!!
